A good number of BIOSes have trouble booting from GPT in non-UEFI mode.
This is commonly reported with Lenovo desktops and laptops (including
X220, X230, T430, and E31) and Dell systems. Although UEFI is the
preferred amd64 boot method on recent hardware, older hardware does not
support UEFI, a user may wish to boot via BIOS/CSM, and some systems
that support UEFI fail to boot FreeBSD via UEFI (such as an old
AMD FX-6100 that I have).
With this change amd64 memsticks remain dual-mode (booting from either
UEFI or CSM); the partitioning type is just switched from GPT to MBR.
The "vestigial swap partition" in the GPT scheme was added in r265017 to
work around some issue with loader's GPT support, so we should not need
it when using MBR.
There is some concern that future UEFI systems may not boot from MBR,
but I am not aware of any today. In any case the likely path forward
for our installers is to migrate to CD/USB combo images, and if it
becomes necessary introduce a separate memstick specifically for the
MBR BIOS/CSM case.

This is a minimal fix for ARM images, in order to safely MFC it before
11.2-RELEASE. Afterwards, however, I believe we should actually just change
the default (as in, etc/defaults/rc.conf). The reason is that it's required
for every image that's being cross-built, as kldxref(1) cannot handle files
for non-native architectures. For the one that is not - amd64 - having it
on by default doesn't change anything - the script is noop if the linker.hints
already exists.
The long-term solution would be to rewrite kldxref(1) to handle other
architectures, and generate linker.hints at build time.

This keeps the existing El Torito entries for BIOS and UEFI boot code and
adds a GPT in the ISO image's System Area containing boot code for BIOS that
will load /boot/loader from the ISO filesystem and execute it. We then use
etdump to find the EFI System Partition image in the El Torito catalog and
add an entry to the GPT that allows EFI to find it.

Some BIOSes have trouble booting from GPT in non-UEFI mode. This is

currently support booting FreeBSD/i386 via UEFI there's no reason to
prefer GPT.
The "vestigial swap partition" was added in r265017 to work around an

We may want to make the same change to amd64, although the issue there is
mitigated by such systems booting via UEFI in the common case.

UEFI booting requires an EFI System Partition (ESP). On most storage devices
this will be in a specific partition type. To allow booting from CD/ISO
filesystems, UEFI will look for an ESP in the form of a FAT filesystem image
embedded in the image. Historically FreeBSD has added one of these to its
amd64 ISO images but marked it as simply another i386 boot image. Luckily for
us most UEFI implementations are rather forgiving and work this out for us.
This change adds the ability to mark a boot image as being a UEFI image. It
also modifies our ISO generation to use this marking for the UEFI image we
embed.

kernel.ucl uses a hardcoded boot/kernel for kldxref, which is the incorrect
directory when we're installing extra kernels that aren't the "default"
kernel (placed at boot/kernel).
Fix this by instead using a new %KERNELDIR% that we now replace in
Makefile.inc1 with "kernel" for the default kernel and "kernel.${_kernel}"
for these extra kernels so that, e.g. /boot/kernel.SHIVA, will get properly
kldxref'd upon update and avoid outdated linker.hints.

The Pine64 root filesystem was incorrectly created directly on the MBR
partition. This can cause the loader to get confused when loading the
kernel from this filesystem.
The loader will see this as a small partition meaning later checks to
ensure it doesn't read past the end of the disk incorrectly report a
failure. This seems to work mostly by accident with the released images as
they are smaller than the reported size, however after growfs has run the
image may no longer boot.

Since Amazon provides NTP servers within their network, this should
be far superior to using the default NTP pools; and since the service

able to compromise EC2 instances even without ntpd running...)

Relnotes: EC2 instances now keep their clocks synchronized using
the Amazon Time Sync Service (aka. NTP).
EC2 instances are normally launched with an SSH public key specified,
which is then used for logging in (by default, as 'ec2-user'). Having
ChallengeResponseAuthentication enabled (as FreeBSD's default sshd_config
does) has no functional effect in a new EC2 instance, since you can't log
in using a password until a password has been set -- but having this
enabled results in alerts from automated scanning tools which can detect
that sshd advertises support for keyboard-interactive logins (since they
can't detect that accounts have no password set).
EC2 users who want to use passwords to log in to their instances will need
to set 'ChallengeResponseAuthentication yes' in FreeBSD 12.0 and later.
